C. openflow instance sales mode passive
D. openflow instance sales mode hybrid
Correct Answer: C
Explanation/Reference:
Explanation: OpenFlow instance mode
OpenFlow can work either in active or passive mode.
Passive mode
There is one-way communication from the OpenFlow controller to the switch. Packets that do not match any flow in the flow table on the switch are not sent to the controller. Such packets of new flows are handled normally by the switch.
Active mode
New packets of a flow that the switch is not aware of are sent to the OpenFlow controller.
